Clock

The face or dial of a watch is a circle whose outline is partitioned into 60 equivalent amounts of segments called time . A timekeeper has two hands, the shorter one is known as the hour hand or short hand while the bigger one is known as the time hand or long hand.

1. In an hour, the time hand cover 55 minutes on the hour hand.
2. In consistently, both the hands concur once each hour.
3. The hands are in the same straight line when they are incidental or inverse to one another.
4. Edge covered by hour hand in 12 hrs = 360°
5. Angel covered by time hand in 60 min. = 360°
6. The hour are 30° apart. (360°/12 = 30°)
7. The minute are 6° apart. (360°/60 = 6°)
8. When the two hands are at rights angles 90°, they are 90/6 = 15 minutes apart. This occurs twice in every hour.
9. When the two hands are in opposite directions, they are 180/6 = 30 minutes apart. This occurs once in each hour.
10. When the hands coincide, they are 00 and zero minutes apart.

Too quick:
If a watch showed higher time to real time then it is said to be quick. For example, If a watch or a clock shows 8.15, when the right time is 8, it is said to be 15 minutes too quick.

Too moderate:
If a watch showed lesser time to real time then it is said to be quick. For example, If it showed 7.45, when the right time is 8,it is said to be 15 minutes too moderate.
